# Digithera QR vs RED control

The clearest difference is update cadence: Digithera QR at every 5 weeks against RED control's every 4 months. RED control's advantage is iOS requirement (13.0 vs 17.2). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Digithera QR ships an update every 5 weeks, RED control every 4 months. The most recent releases landed on October 7, 2026 and October 2, 2026 respectively.
